As av means fornpropelhng arid-driving` the i Thethreshjn machine is provided'with a transversl ba anced case 10', with afront yoke, and with'a rear axle 12 which is'also in the form` oan' a'proximately rectangular frame or yoke. T crear wheels 13 are journaledon` trunnions 14 of the rear axle frame by vertical pivot joints 17.

turned, for a'purpose which will hereinafter appear.

A second balancing beam 24 similar to the beam 18 is intermediatelypivoted at 25 to the central upper portion of the forward axle frame 11.rlhis beam 24 and the said axle frames 11 work in a vertical slot 26formed in the front ends of the sides of the case 10. adjusting rod 27is swveled at its central portion to a lug 24a on the central portion ofthe balancing .beam 24, and at its end portions has threaded engagementwith nut blocks 28 on the sides of. the case 10. These nut blocks arepartly shown in Fig. 10, and the arrangement is the same as that of therod 21, At one end, the rod 27 is provided with a hand wheel 29, bymeans of whichit may be rotated. The front portion of the case 10 restsupon and is supported by the end portions of the-balancing beam 24.

rlhe. ivotal c' uinections 19 and 25 are above t 1e center of gravity ofthe case 10 and parts carried thereby, and hence, it is evident that thecase when properly balanced will maintain an upright or a verticalposition when` the axle frames 11 and 12 are oscillated vertically outof 'true horizontal positions. It is also evident that the said axleframes 1 1 and 1 2 are free to oscillatevertically in the slots 26 and20, res ectively, of the case,vand that the said slots old the said axleframes securely against rotation.v By the proper rotation of thethreaded adjusting rods 21 and 27, the case 10 may be slid laterally onthe ends of the balancing beams 18 and 24, so

as to set the said case in balance transversely,

such adjustment being necessary in order to compensate for the variousdevices carried by or mounted on the said case.

The threshing machine is shown as connected tothe rear-.portion of theengine platform or frame 1 by a draw bar 30, detachably pivoted to saidplatform at 31 and-detachably coupled (see Figs. 6 and 7) to a lug 32 onthe upper central portion of the front axle 11.

The rear portionof the draft bar 30 is conother liquid rom the one dashpot to the other. The pistons 36 are connected by llinks 39 to arms 40secured to and projecting from the opposite sides of the case 10. Thesedash pots and pistons prevent a pendulumlike lateral swinging movementof the case the case 10.

10, and cause the same to maintain a vertical position. Mounted in theextreme forward portion of the case 10, is a threshing cylinder 41 andcoperatin `toothed concave 42, from the latter of whic an inclined deck43 projects forward.

In front of the deck 43 is 'a grain pick-up device which preferablycomprises several coperating devices, to-wit; A forwardly inclined frame44 is pivotally connected by a shaft 45 to the sides of the front of thecase 10. The free forwardly projected end of this frame 44 is supported4by a ground engaging roller 46 and its weight is partly sustained by aspring 47 that connects a rearwardly extended arm 44a of said frame to afixed part of the case v10, as best shown in Fig. 4.

The numeral 48 indicates a grain pick-up fork secured to the front endof the frame 44, and 48HL indicates side tines, shown as secured to theside boards 44b of said frame 44. The fork 48 is preferably adjustableto different heights, and the tines thereof are preferably yieldinglysupported for independent upward pivotal movements in passing over anobstruction.

The frame 44 carries a pair of rollers.49 and 50, the shaft 45 of thelatter of which is at the pivotal connection of said frame 'to Anendless conveyer belt or slatted canvas 51 runs over the rollers 49 and50 and serves to carry the grain from -ihe fork 48 to the deck 43.

Atoothed roller 52 overlics the fork 48 and is supported by a pair ofarms 53 pivoted on the shaft 45. Spring devices 54 yieldingly supportthe'arms 53 from the pivoted frame 44, as best shown in Figs. 4 and 6.Another toothedaoller 55 ovcrlies the receiving end of the deck 43, andthe shaft thereof is journalcd in the sides of the case 10.

A channel shaped grate 56 inclines upward and rearward from thethreshing concave 42, and delivers onto a straw rattle or conveyor 57 ofthe usual or any suitable type. 'lhis rattle' or conveyer runs oversuitable rollers 58, 58, mounted in the sides of a stack forming section10 ofthe case 10. A toothed endless elevator belt 59 works over theinclined grate 56 and runs over rollers 60, 60,

The threshing cylinder 41 is driven from the engine 7 through a knucklejointed shaft 63 having a telescopically adjustable intermediate section631. One end section of this shaft 63 'is connected to the crank shaftof the engine 7 by miter gears 64, and thc other end section of saidshaft is connected to the shaft of said threshing cylinder by mitergears 65,

'- The conveyer belt or apron 51 on the pivoted frame 44 of the grainpick-up device seance is driven 4from a bevel gear 66 carried by one I'111g a telescopically adjustable intermediate section 6782.

shaft is connected to the shaftofftheroller over the grate 56 by thetoothed conveyer'f" 59. .The grain dropped through the grate and throughthe concave 42 wil bythe conveyer 61 and will be delivered onto thereceiving member, such as'the grain pan, of the separating mechanismproper, or, otherwise stated, the vibra-tory sieve mech anism. Inaccordance with one of the im-v portant features of my presentinvention, I

v mount these vibratory sievesor screens and preferably also certainother coperating parts,'such as the grain panand fan, on a supportingframe which is balanced and held level in a direction transversely ofthemachine by-the transversely balanced machine case 10, and in adirection longitudinally of tended arms 80El that are pivotal themachine, it is held levelby an automatic leveling device of novelconstruction. This balanced frame -is shown as rectangular in formmounted on a heavy transversely extended bearing sleeve 71, the ends ofwhich are secured in bearing boxes 72 ('see` Fig. 11), rigidly secured.in theslots r 20 and to the sides ofthe case 10. A counter-shaft 7 3extends through the sleeve ,71 and at one end isl provided with a pulleyv74., and at its other end with a pulley 75. The frame 70 sup-v ports adepending fan case 76 and lnclined' deck 76a. The numeral'77 indicates achafing sieve, and the numeral 78 indicates the usual grain panconnected thereto byl a hinge 77.?. ln the sides of the frame70 aremounted five transversely extended rock shafts `7 9, 80 8l, 82 and 83.The shaft 80 has ulpwardly exy connected to the sieve 77. The shafts 82and '83 are provide-d with arms 82a and 83 a, respectively, that arepivotally connected to the grain pan 78. The ock shafts 79 and 81 areprovided with depending arms 79 .and 81", that support a vibratory grainsieve 84. `The rock shaft 81 is also provided with 'an upwardly extendedarm 81b that is connected to the uprer end of one of the arms 82a by ashort lin 85 These connections cause the pan 78 and chaing sieve 77 tomove simultaneously in the same direction, and the sieve 84 to the`movement thereof.

vThe frontend sectionof the" shaft63 is connected tothe gear 66 by' abevelpinion. 66, and the rear 'end section of said:

be elevated v.closed to any desired extent.

and at its central portion is pivotallyove simultaneously in directionsreverse to In one end of the frame 7-0 'is journaled a crank shaft 86that isI 'i connected by 'a pair ef pitmen 87 to the sides v.of thegrain pan 78. The rock shaft ,'80 is provided'with short arms 80h thatsup port the upper end of a vibratory inclinedw deck 88, the lower endof which rides uponV the deck 761. deck 88 delivers ,the cleaned grain'intolthe usual auger-equipped spout 89; ,I

Working in the fan case 76 is a fan head 90, theshaft 90aof Which isprovided at one end with a'pulley 91, andat lts other end with apullcy'92. A belt 93.runs over the pulleys 74 a d 91 to transmit motionfrom Athe shaft 73 to the fan shaft 90, and a belt 94 runs over theulley 92 and cran shaft 86, to impart motion to the latter.

R1gidlysecuredto the sides of the case 10, one below each end .of thepivoted'frame 70, 1s "a pair. of elongated'dash pots or boxes thatextend preferabl from one side to the other of said case. T ese dashpots or boxes 95 are connected by a pipe 96 preferably having a valveadapted to be opened and Working with' acting iipats 97 in the dash pots95 are piston which, by links 98, are connected to t 1e ends of thepivoted frame 70. lThe dash pots or boxes 95 are preferably made large,so that they are adapted to contain a very considerable amount of oil,water or other liquid, indicated' by the character z.

I provide means for counterbalancing the frame 70 and parts carriedthereby so that the dash (pots and pistons operated upon by the 'li ui zand under gravity, may maintain` t e sieves which are carried by theframe 70 in horizontal or predetermined approximately horizontalpositions. This counterbalanc-ing device, as shown, comprises apair oflevers 99 that are ivoted at 99a to the sides of the case 10 and) areprovided with adjustable links 100 adapted to be applied to either endthereof: Links 101 connect said levers 99' to the rear end of the frame70'. Of the other driving connections of the machine, it is onlydesirable to note as follows: On the right hand end of the cylin dershaft (See Fig. 2) is a pulley 102, and on the right hand end of theshaft of the roller 60 is apulley 103.- The numeral 104 indicates a beltwhich runsover the ulleys 102, 103, 75, over an idle guide pul ey 105and over a ulley 106 on the shaft of the roller 58. eft hand end, theshaft of the roller 60 1s provided with two ulleys 107 and 108, an onits left hand end) the shaft of the roller 62 is provided with a pulley109. On the left hand end of the shaft of the roller 58 is a pulley 110overwhich and the pulley 109 runs a short belt 111 (see dotted lines Fi3). On the right hand end of the shaft o the toothed feed roller '55-(see Fig. 6) is a pulley over a pulley 86a on the l The numeral 113indicates a countershaft journaled in the sides of the case 10 andprovided at its right hand end with a pulley 114 over which and thepulley 112 runs a beltl 115. On the left hand end of the counteishaftllis a ulley 116 over which and the pulley 108 of tlie roller 60 runs abelt 117 (see dotted lines in Fig. 3). The pulley 1.07 serves to driveone of the grain elevators of the machine, the construction andarrangement of which it is not necessary to consi er for the purposes ofthis case.

As already described, the case 10 and parts carriedthereby will becounter oised or balanced so that the said case wi l stand in anoscillatory movement thereto being on the p pivotal connections 19 and'25.

, of this class of machines.

The importance of maintaining the sieves 7 7-84 and pan 78 in an api'oxiinately horizontal or predeterinine osition is well known by allpersons fami iar with the use For, different kinds of work, aslightinclinationV thereof longitudinally of the machine is desired, but theinclination having been-determined, it is desirable to maintain thesaine with respect to a horizontal, regardless ofwhether the machine istraveling up hill or down hill. Thel predetermined adjustment of thesaid sieves and pan, and, hence, of course, of the pivoted frame 7 0, isregulated by the adjustment ofthe weights 100 on the counterbalancingarms 99. In running down hill, the water .e will run from the rear dashpot 95 into the frontdash pot 95 and will raise the front float 97 so asto thereby maintain the predetermined position of the frame 70, sievesand Y pan carried thereby. Inrunning up hill, the

lwater will run from the forward dashV pot 95 into the rear dash pot 95and will raise the rear float 97 and thereby maintain the predeterminedposition of said frame 70 and parts carried thereby.

The wheels of the traction engine, as well as the wheels of'thethreshing machine are, as is evident, arranged to straddle or run onopposite. sides of the windrow of grain which is being picked up andthreshed by the machine. the first instance, is, under the advancemovement of the machine, picked up and raised in the first instance bythe fork 48, and when slightly raised is taken up by the endlessconveyer belt 51 and is fed to the threshing cylinder and concave, itsupward movement being further facilitated by the aciion thereof of thetoothed overhead rollers 52- and 55. The grain dropped through theconcave' is carried upward b'y the conveyer belt 61 ,and is deliveredinto the grain pan 78, while 4 speed of the threshing rig.

The loose grain of the windrow, in.

the deliveryend of the stack 10a. The extensible knuckle jointed shafts63 and 67, of course, permit the required pivotal movements of thetraction engine with respect to the threshing machine. It is importanttonote that the belt 51 and toothed roller 52 of the grain pick-up deviceis driven fioin one of the traction wheels and the traction engine, and,hence, will always be driven at a speed which is in proportion to theadvance The frame 44 of the ick up device is, of course, free forvertica 'inovenients to adapt itself to irregularities in the ground.The toothed roller 52 is supported by the springs 54 in such manner thatit may freely rise and fall to adapt itself tothe thickness of the grainwhich is be.

ing fed upward from the fork 48 to thebelt 51. From the forgoingdescription it is thought to be evident that by the use of a threshingrig of the character above described, grain loosely deposited inwindrows may be picked up and tlireslied in a highly efficient manner Sofar as the broad idea of this invention is concerned, it will beunderstood lthat the threshing machine may be driven by any suitablepower, either mechanical or animal What I claim is:
